Wells Score

This App contains the two Wells scores that aid the diagnosis of low risk deep vein thrombosis (DVT) and pulmonary embolus (PE). It is for use by suitably trained medics and as always with these scores they are only an aid and should always be used in conjunction with local guidelines.

The two scores operate independently of one another, where the questions overlap with differences these are highlighted. The only point of note here is that the question “Clinical signs and symptoms of DVT (minimum of leg swelling and pain with palpation of the deep veins)” in the PE score and worth three points is replaced by the three questions relating to pain and swelling within the original DVT score. A tick on the question relating to tenderness along the deep veins and one or both of the questions relating to swelling (over 3cm... or of the whole leg) will allocate the three points correctly to the PE score. Of course if you are scoring a DVT then the score accumulates as you might expect.

If the text is too small simply tap it to get a larger view then tap again or press the 'back' button to dismiss. The references and information about the App are available via the menu button. Tapping the “Use this because..” will bring up the two level score outcomes. Suggestions are welcome. Suitable for general practitioners, community nurses, specialist nurses, registrars, other junior doctors and medical students.
